INKING ROLLER.

Application filed December 2, 1922. Serial No. 604,514.

The invention relates to improvements in inking rollers for printing presses for evenly distributing, transferring and applying the ink betvveen a series of cylinders or rollers 6 or to the plate cylinders or forms of the justable sockets or bearings provided withl hinged caps secured by hinge bolts and thumb-nuts, the caps being adapted to detachably hold the roller in the bearings. Such rollers and bearings are objectional in many Ways, as the rollers are apt to be out of balance and to run eccentric if the journal ends or Shanks become bent or sprung. The hearings are also liable to run hot if not continuously lubricated. To disengage a roller thus mounted from contact with cooperating cylinders it must be removed from the press, tivo operators being usually employed in disconnecting or setting the same, or one operator must go successively to opposite ends thereof for this purpose. Also under this arrangement difficulty frequently occurs 1n making the necessary socket or bearing adjustments on account of their inaccessible positions on the machine.

Among the objects of the present invention is to provide means whereby a roller may be introduced into the press and temporarily supported at its opposite ends upon convenient rests and from there transferred to bearings or bushings having means by which to shift the roller into and out of operative inking position relative to adjacent rollers or cylinders. the shifting movements being accomplished by a single operator from one side of the machine.

A further object is to provide means for adjusting the opposite ends of the inking roller independentlyof each other and in operative relation with a pair of adjacent cylinders in such manner that an', adjustment With respect to either one of the latter will unaffect the other. i

Another object of my invention is to provide means for throwing the roller out of mking contact with vboth of said cylinders simultaneously by a single movement of a handle, leaving the roller in position to be removed from the press, or to be again moved into inking contact, and also for means for locking the handle in both positions.

A further object of the invention is to provide means for reducing the running friction of the rollers to a minimum by introducing anti-friction ball or roller bearings into the ends of the rollers, whereby the roll.- er shafts become non-rotative when in operation, With the result that the rollers will run true even though the roller shafts may become slightly bent or sprung. The roller shafts may be made as stiff as desired without increasing the friction, Weight or inertia of the running element. My improved ccn-` struction holds the inking rollers so rigidly that vibration of the rollers is practically eliminated, hence they have no tendency to deflect into the gaps and gullies of the typeform and thereby cause streaks of alternate intensity and faintness in the printing.

Vilhile the improvements herein are especially adapted to form rollers of high speed rotary newspaper pressesor the like, they are also applicableto other ink trans fer rollers in such presses.

For further comprehension of the invention, and of the objects and advantages thereof, reference is had to the following description and accompanying drawings, and to the appended claims .in lwhich the various features of the invention are more particularly pointed out.

In the drawings, Fig. 1 is a general View of my improved ink roller as applied to a printingpress. Fig. 2 is an enlarged side view of the bearing for supporting the roller, showing one end of the lat-ter in section, taken on line 2-2 of Fig. 3. Fig. 3 is a vieiv taken in vertical section on line 3--8 of Fig. 5 and showing the parte' in position to receive or tev release the roller' er to retain it out of inlting` Contact. Fig. 4 is a View similar to that of Fig. 3, but showingthe roller after being moved into operative position. Fig'. 5 is a horizontal sectional View on line 5-5 ot' Fig. Fig'. 6 is an ison'ietrical vieu* o'lI a bracket bearingl tor the support of the roller. Fie'. 7 is an isometrical Yiew ot`v one ot the bushings provided with an operating handle. And Fig. 8 is an iscnietrical' View of one end of the roller shaft;

Referring; to the drawings, numeral 10 indicates; al it'orin or plate cylinter; 11, an ink distributing cylinder, and 195, thefoppoy site traines ot a printing press in which the rotating' elements are inounted;

rilhe inking' roller 13 consists preferabl7 of a tube 14., the' outer surfae ot'wliicliis covered with v the usual composition, or rubber orth'e lili, ii'idica'ted` at' 15. A shaft 16 extends longitudinally through the roller and .projects at opposite ends to engage supportingineinbei's. The roller 13' is mounted to .revolve treelyupon theshatt. by ineans ot the anti-friction bearings 17, preferably of the ball bearingv type, arranged in the opposite ends oit the tube, and which latter ends are comiterboreo` at 18 to 'torio internal shouldersk 19. The shaft-d6 is slightly reduced iny diaineter at each end at' 2O to torni :r4 shoulder 21.l and the ball learin are snugly fitted into the counterbores 18 and upon the shaft` at. 2O and against the shoulders 19and A; collarf) is mounted on the shattand secured. thereto by the setscrow f2.3. the collar being4 pretertdilyT disposed a short distance within the tube 1111 to' pi went the entrance of' dust. The parte` are so fitted and assembled Athat theV roller may be free to rotate upon the shaft butwithout lateral or longitudinal loss motion thereof, the shaft being` preterably turtlie-i.' reduced iu diainetcr at to facilitatev :1,finlilingr- The shaft is also provided at its oppositel ends with handles and'u'ith oppositelf,7V

liattened 'ii-aces The roller` shaitt 1G is s oi'ipositc ends by theV broche the opposite press-trames 12 by the upper andl lower stud-bolts 25 and QT, the bolts beingl similar and; each provided with a upportod at its 25, secured to squared portion fitting freely in corre sponding'lysquared recesses 30 .in the brackets. Screws 31 are freely fitted in the brackets andere provided With heads the inner ends ot the screvs being threaded throughI the squared portion of the studbolts 26 and 2?, `Whereb)v thel rockets may be adjusted with respect to the cylinders 1Q and 11.

The `stud-bolt 26 vis preterablV7 located at al point onthc press-traine coinciding `with aneXt/ension ai line-representing the contact point betujeen.y the.' roller 13 and 'the cylinder 1.0,.andthe studbolt- 27 iscorrer spondinglj.' located with respect to the roller Si and the cylinder 11, as indicated in Fig. 4t; and by adjusting' the screws 3l in 'the respective stud-bolts the opposite ends of the roller 13 may be adjusted indepcndcnil)7 ot each other and with respect to either ot the cilinders 10 and 11 to obtain thedesired operative pressure therebetween. `With the sind-bolts as thus positioned, it will be evident; that in' the adjustment ofA the roller with respect to either one of the cylinders, the stud-boit oi? the opposite cylinder' will act as' a pivotal center for 'such niorenient.y and the existi adjustment relativo to said opposite cylinder-be' unaffected thereby. It isalso to be understood that these contacts or operative engi'igenients are made only occasionally and through an eritreinelr sinall distance at a time in orderto provide tor the n'ear and shrinlnigel oty 'the con'iposi tion roller 13, and when the adjustments havebeen niade` the nuts 28 are tightened to retain the brackets 25 .in their adjusted Aiosition.

The opposite brackets 25 are boredv at to torni bearings for tl'ierro'tatii'e' support ot' the bushings 34, which latterare provided with transversesiots or openings entending from the periphery toward and beyond the centerfthereot and'adapted to aline with each other as positioned in the opposite brackets vfor lthe engagement b5 the ol sitely flattened tacos 33 at the ends sl 16, the latter, in thev rotative movement o' the bushings, loe/isf'Y arrangecil to be locicf therein and held against displacement. as shown in Fig'.

bottom` Wall'ot the openings loin the b i. ings 3st when'A the latter areiu open g tion, as indicated in Figi; 3,' and in um position the roller-shaft 1G may readily be introduced or Withdrawn' 'from the hushings, or held teniimiwirilj.Y upon tl e rests f' One ot the lnisliiugs, :it tho operat ne; side the machine. is pro idea with an acti Y handle 38, shown inv dotted lines in litige and it, in resp'ectivel;v open and' closed tions, the actuating handle being i with a latch-lever 39, pif'otall)v n'i'ounteil thereon at t0 and provided with 'a hitch-pin 4:1 arranged to engage latcb-hole'fy i12 and fifi in the bracket 25. A spring let is dist-posed between the pivotally connectcdhandle and lever to norrnallj,7 urge the latch-pin into the lat-ohlhol'es, the latter beingsuitabljyv pcsition'ed to hold the bushing/'in its ext-renie' ot opposite movements, the "releasethereot being lll) "effected by a pressure upon the `free end of shoulders being adapted to hold the handle- Y bushing against endvvise movement Within the bracket bearing, its vlateral position therein being maintained by the relatively small gap space at 48 as compared with the diameter of the bushing. To provide for the endivise connection and disconnection between the bracket and bushing, the peripheral length of the shoulder 46 of the latter is made somewhat less than the gap space at 48, and by effecting their respective registration the bushing` may be readily inserted or Withdrawn, it being,` understood that the bushing in the opposite bracket bearing is provided vvith similar projecting shoulders at its opposite ends. ln the position shovvn in Fig. 4, it Will be obvious that by turning the handle bushing as thus engaged with the flattened surfaces of the shaft 16, the latter will be correspondingly rotated and in turn will likewise rotate the bushing' in the oppositie bracket. As indicated in the figure the center 49 of the shaft is disposed eccentrically in the bushing with respect to the rotative center 50 thereof, and in the normal movement of the latter, respectively shown in opposite extremes in Figs. 3 and 4, the roller 153 mounted on said shaft is adapted to be moved from an inoperative into an operative position with respect to the cylinders l() and 1l, the stiffness of the shaft 16 being suflicient to equally operate the opposite ends of the roller Without spring` or vibration.

The inking' roller as thus arranged is adapted to operate in connection With a single roller or cylinder, or With a pair of cylinders, as shown, and a single operator stationed at one side of the machine may quickly shift the roller by means of the handle 38 either into or out of operative position With little or no loss of time, a matter of considerable advantage in the larger type of machines Where numerous rollers are employed and frequent short etoppae'es required for inspection of the printed Work.

It will be observed that the actuatinghandle Iand the adjusting screws are all arranged on the outside of the frames and away from the train of gearing which is generally placed between the forni cylinder l0 and the ink distributinp,r cylinder il, a shown in Fig. l,

While I have shown and described the preferred construction and arrangement of the several devices and the manner in Weich they co-operate to accomplish tne desired result, it is to be understood that various detail changes may be made in the several parts Without departingl from the essential principle and scope of the invention.
